CURB-CUTTER.

SPECIFICATION forming part of Letters Patent 310.271,96), dated February 6, 1883.

Application filed September 9, 18852. (No model.) i

other head-plate by screws, bolts, or rivets,

and having a twist near the head, so that the plane of the cutting portion of the blade shall be at right angles with that of the head-plate andthe knives at equal distances apart; also, in combining with them one or more stays or cross-blades in two or more parts, with slots in their outer edges, the purpose of which will be presently explained; also, in certain other details of construction hereinafter more specilically described and shown.

The object of my invention is to constructa dairy-knife or curd-cutter'that shall be lighter and simpler in construction than those heretofore used, also one in which a wider crossblade than heretofore is provided and the liability ofdisplacement or slipping of the blades upon the stay or cross-blade prevented, and the blades rigidly braced apartand securely held imposition, thus securing absolute uniformity in their operation.

In thedrawings, Figurel is afront view of my curd-cutter. Fig. 2is a sectional side elevation through the line yy. Fig. 3 is a vertical crosssection through the line a.' showin g the crossblade or stay. Fig. 4 is a detail view showing section of the stay or cross-blade in position. Fig. 5 isa section of one of the parts of the cross-blade, showing theslots in its edge. Fig. 6 is a detail view showing a modication in the form of the cross-blade. Fig. 7 `is also a detail view showing a modification in the form of the cross-blade. Fig. 8 is a section of one of the blades, showing the slot or openin g in the blade through which the stay or crossblade is inserted. y

In dairy-knives` as heretofore constructed various forms of head have been used, all of which are more or less cumbersomewas it has been found difficult to secure the necessary" strength and rigidity without the u-seof cousiderable material, as in all cases the blade has been inserted at right angles to the line of vthe head, requiring either a solid head or a construction, which is as follows I provide a single plate, A, for` the head, which may be composed either of `metal or of wood. The blades of which my knife are cornposed are then given a half-twist at the end near the head, as shown at ct, Fig. l, so that a flat surface of their entire width is presented for contact with the head, and they are secured thereto by screws or bolts, so that they may be readily removed, or they may be firmly riveted thereto. By this twist the plane of the cutting portion of the blades is made to assume a position at right angles w ith that of the head and the cutting-ed ges ranged side by side at suitable distances apart. These distances are uniformly and securely maintained by means of the stays or cross-blades G, which are constructed in two or more parts, b c d, as shown in Figs. 4, 6 and 7.

b and d represent the parts of which the cross-blade proper is composed, which are simi; lar inconstruction, and when joined or united at their backs they form a continuous blade slightly less in width than the others and corresponding in length to the width of the knife. They are sharpened on their outer edge and provided with slots e, as shown in Fig. 5, corresponding in number to the blades B and in width to the thickness of the blades.

A horizontal slot, H, is formed through the long blades B, which is in length one-half the width of the blade G when in place, but in width equal to double its thickness. The two sections, b d, are then inserted through this slot and forced into position, so that their backs will be in contact and their edges outward, and the blades B will fill the space formed by the slots e. The key-piece c is then inserted `be- IOO neath and riveted or soldered at its youter ends, fi, and serves to completely fill the space H and confine the parts of the cross-blade or stay C in its place, as shown in Fig. 4:, and the openings or slots e occupied by the blades B serve to firmly brace them in position and efi'ectually prevent any lateral movement. By this construction a wider cross-blade may be employed than formerly without weakening or reducing the strength of the blades B, as would be the case were the horizontal slot equal in length to the width of the cross-blade. I do not, however, confine my construction to placing the key o beneath or alongside of the parts composing the cross-blade, as above shown; but it may be placed in rear of one of the parts, asshown in Fig. 6, in which case itsouter edge may be sharpened; or it may be placed between them, as shown in Fig. 7. When either of these constructions are employed the horizontal slot H in the blades B need only correspond in width to one thickknife having a series of separate doul'ileedgedA parallel blades, twisted at one end and secured to a head-plate in such manner that the plane of the cutting portion of each blade shall be at right angles with the head, substantially as and for the purpose described.

2. The combination, in a curd-cutter, of

separate parallel double-edged blades secured to a head-plate, with a sectional cross-blade having slots in one or both of its outer edges,

said cross-blade passing through slots in thel parallel blades, said slots being of less length than the width of the cross-blades and of suflcient width to permit the insertion of the crossblade and locking device, substantially as and for the purpose described.

3. A dairy-knife consisting ot' a head-plate and handle, a series of separate double-edged blades, made as described, and secured to the head-plate, and one or more cross-blades slotted in their outer edges and entering slots in the cutting-knives, and secured thereto by suitable keys, substantially as and for the purpose set forth.

4. The combination, in a dairy-knife or curdcutter, of the head-plate A, the series of doubleedged parallel blades B, provided with the twists a near their head, whereby a flat surface is brought into contact with and secured to the head-plate, and the sectional stay or cross-blade C, having slots e, whereby a wide cross-blade is provided without weakening the blades B, and the parallel blades and crossblades are rmly and securely braced and locked in position by a suitable locking device, substantially as and for the purpose set forth.

[n testimony whereof I affix my signature in presence of two witnesses.
